Method
Preparation
Preheat your oven to 350°F (175°C). Grease and flour an 8-inch round cake pan.
Whisk together the flour, cocoa powder, baking powder, baking soda, and salt in a medium bowl.
Beat the softened butter and sugar in a large bowl until light and fluffy, about 3–4 minutes.
Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
Combine the dry ingredients with the butter mixture gradually, alternating with buttermilk and whiskey.
Pour the batter into your prepared cake pan and bake for 30–35 minutes.
Let it cool in the pan for 10 minutes before transferring to a wire rack.
Ganache Preparation
Heat the heavy cream in a small saucepan over medium heat until it simmers, then remove from heat.
Mix in the dark chocolate chips and let it sit for 2 minutes. Stir until smooth.
Incorporate the whiskey into the ganache until fully combined.
Assembling the Cake
Assemble your cake by placing it on a serving plate and pouring ganache over the top.
Chill the cake for 30 minutes if desired for a firmer ganache.
Optional: Garnish with chocolate shavings or a sprinkle of sea salt.
Notes
Ensure that your butter is softened for easy creaming with the sugar. Be careful not to overmix the batter. Use high-quality chocolate for the ganache for the best flavor.
